Tay,

Quickly glossing over the code, what I understand is, it is breaking while
evaluating one of the conditions mentioned in your re-write rules:


RewriteCond %{REQUEST_FILENAME} !-f
>
> RewriteCond %{REQUEST_FILENAME} !-d
>
> RewriteCond %{REQUEST_URI} !index

Basically it is trying to locate %{REQUEST_FILENAME}%, to evaluate these
conditions. But that file path is being evaluated to NULL, and this confirm
with your request:
"GET /web/ HTTP/1.1" 500 2990

assuming your "web" is your application resource root, the path relative to
this root is NULL.

Can you please try, something like:

GET /web/someXYZ.jsp

and it should NOT complained about path being NULL.

Once this is confirmed you can then find a way to handle this NULL path in
re-write rule.

Regards,
Ameer Mawia
